Consistencia interna de la escala para discriminación mayor en estudiantes de medicina

Adalberto Campo-Arias, Heidi Cecilia Oviedo-Acevedo, Edwin Herazo-Acevedo

Resumen


Introducción: la Escala para Discriminación Mayor (EDM) es un instrumento de nueve puntos para cuantificar las situaciones de discriminación ─alguna vez en la vida─. En los Estados Unidos, la EDM mostró una alta confiabilidad, aunque, la confiabilidad se debe conocer en colectivos colombianos.

Objetivo: estimar la consistencia interna de la EDM en los estudiantes de Medicina de Bucaramanga-Colombia.

Materiales y métodos: un total de 361 estudiantes de Medicina completaron la EMD. La media para la edad de los participantes fue 20.1 años (DE=1.9); el 59.6% de los estudiantes eran mujeres. La confiabilidad se calculó con el coeficiente de Kuder-Ri­chardson (K-R) y la omega McDonald.

Resultados: la EMD mostró alta consistencia interna, coeficiente K-R de 0.76 y omega de McDonald de 0.85.

Conclusión: la EMD es un instrumento con alta consistencia interna en estudiantes de Medicina de Bucaramanga-Colombia. Se puede usar este instrumento para la investi­gación de experiencias mayores de discriminación en estudiantes de Medicina. Rev. cienc.biomed.2016;7(2):234-239.

SUMMARY

Introduction: the Major Discrimination Scale (MDS) is a 9-item instrument to quantify situations of discrimination at some point in life. In the United States of America, the MDS showed high reliability, although, its reliability needs to be proven among Colom­bian people.

Objective: to estimate the reliability of MDS in Medicine students in Bucaramanga- Colombia.

Material and methods: the MDS was completed with 361 Medicine students. The average age was 20.1 years (SD=1.9), where the 59.6% were women. Reliability was calculated with Kuder-Richardson (K-R) coefficient and McDonald’s omega.

Results: the MDS showed high internal consistency. The K-R coefficient was 0.76 and omega coefficient 0.85.

Conclusion: the MDS presents a high internal consistency among Medicine students from Bucaramanga-Colombia. The MDS may use to measure major experiences of dis­crimination in Medicine Colombian students. Rev.cienc.biomed.2016;7(2):234-239.
